Clearwater, Florida -- Pinellas deputies say they have shot and killed a man who had just stabbed his mother to death.

The man, who has not been identified at this time, reportedly called police around 12:15 p.m., saying he had stabbed his mother and wanted to turn himself in.

Arriving deputies knocked on his door on Pine Cone Circle and saw a man, later identified as 36-year-old Justin Tucker, inside yelling and walking down the stairs toward them. Deputies say they repeatedly ordered him to stop, but he exited the townhouse and continued walking towards them with something in his hand. As he continued approaching the deputies, they reportedly told him to stop repeatedly and when he didn't they opened fire, killing him.

Inside the townhouse deputies found his mother, 67-year-old Kathryn Clark, stabbed to death with a butcher knife beside her body.
